IMPROVEMENT IN WASHING-MACHIN ES.

Specification forming part of Letters Patent No. 190,552, dated May 8,1877 application filed January 27, 1877.

To all whom it may concern Be it known that I, RAOUL CHARTREY, of thecity and county of San Francisco, and State of California, have inventedImprovements in Washing-Machines; and I do hereby declare the followingto be a full, clear, and exact description thereof, reference heilig hadto the accompanying drawings. y

My invention relatesv to certain improvements in that class ofsteam-power laundrymachines in which a dasher or dashers are rotatedalternately in one direction, and then in another inside of a case, andin which the alternate motion of the dashers is produced by an automaticbelt-shifting device, which is attached to theside of the case.

Heretofore the boxes or bearings in which the moving parts of thisshifting device were supported were made in separate pieces, and thesepieces were attached separately to the side of the case in their properrelative positions withreference to each other. This arrangement wasdefective, because any shrinkshaft, and otherwise simplify and improvethe machine, as hereinafter described.

Referring to the accompanying drawings, Figure l is a perspective viewof my machine. Fig. 2 is a` view of the casting.

Let A represent the cylinder or case, inside of which the dashers aremounted upon the central shaft B. C is the supplementary shaft, in themiddle of which the short screwsection cl is found. This screw-sectionserves to move the traveler or nut e of the belt-shifting device.

ff f f are the boxes or bearings in which the slides g h, move, andthese boxes, as above mentioned, have heretofore been made in separatepieces, and attached separately to the side of the case.

I, however, make a single frame or casting, I, (represented at Fig. 2,)in which I form, or to which I attach, the boxes or bearings, and towhich I also pivot the lower end of the Weighted bar j, which moves theslides g h. I then secure the cast-ing to the side of the case, so thatshrinking or swelling of the case will not affect the relative positionsof the bearings.

The boxes K K, in which the shaft Gis supported, were heretofore simplyattached to the hoops or bands l, which bind the ends of the case, bymaking them form a part of the hoopsi-that is, a lug (shown at 0) wasformed on each end of the box, the hoop was cut short enough to admitthe box between its ends, and the ends of the hoop were then turned up,and a screw or rivet connected them with the lugs on the box.

By my improvement, however, I make a lug only at one end of the box, asrepresented, and this lug I attach, in the ordinary manner, to one endof the hoop or band l. The hoop Vthen passes around the case, and itsopposite end is passed under the opposite end of the box-casting. I theninsert a screw, through the end ofthe casting, through the end of the lhoop, and into the wood ofthe case, thus not 'end of the machine, andmount these pulleys upon the end ofthe shaft C, and thus render themachine more compact.

Having thus described my invention, what I claim, and desire tosecure byLetters Patent is'- 1. The boxes or bearings fffj', all attached to asingle frame-casting, I, which is secured to the side of the case, andto which the lower end of the weighted bar j is also pivoted,substantially as and for the purpose de' scribed.

2. The improvement in connecting the boxes K K with the bands or hoopsl, consisting in attaching one end, N, of each hoop to one end of thecasting by means of a lug, O, on said casting, and inserting theiropposite ends underneath the opposite ends of the boxcasting, andsecuring the whole by a screw,

In Witness whereof I have hereunto set my hand and seal.
